Jason Sudeikis Opens Up About His Son's Name And Jokes About Why He Hasn't Married Olivia Wilde Yet

Jason Sudeikis is finally opening up about the origins of his son's name. Plus the Horrible Bosses 2 actor reveals why he hasn't married Olivia Wilde yet.

When Jason visited The Ellen DeGeneres Show on Thursday, he couldn't help but show off his adorable son Otis Sudeikis. While promoting his new film Horrible Bosses 2, he shared some adorable pictures of his beautiful baby boy (you can see the pictures in the video here).

After Ellen DeGeneres couldn't stop noting how cute Otis is, Jason said, "That's his mom's doing... the majority of it." The We're The Millers actor also admitted that his fiancée is also responsible for naming their son Otis, because she is super cool.

 Rock and roll, baby.

"That's him mom too. She's been a fan of Otis Redding since she was a little girl," he told Ellen. "So she's been cool forever, obviously. Yeah, and I was like that sounds great."

The happy couple welcomed baby Otis in April 2014 and every now-and-then they share a precious picture of their little guy. "Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building! (I'm the building)," Olivia tweeted after giving birth. Olivia was featured in Glamour magazine breastfeeding Otis in its September issue, but since then the couple has kept him sheltered from the press.

Even though they have a child together Jason and Olivia have yet to tie the knot. The couple has been engaged since January 2013 and Jason explained to Ellen why they haven't officially gotten married. The talk show host joked that it was because of the hilarious Ellen portrait above his bed and Jason went along with the hilarious story.

In Glamour's September issue Olivia actually opened up about her future wedding plans with Jason. "We're engaged, but no specific plans yet-we just have to find the time to put it together," she told the publication. "In many ways, a child is more of a commitment. We are fully committed and really happy as a family."
